1 Claim.

My invention relates to fanfold manifold packets, and its object is to improve and simplify the construction of such packets in the manner hereinafter more fully set forth.

In the accompanying drawing which forms a part of this specification,

Figure 1 is a plan view, partly in perspective, of a manifolding packet embodying my invention.

Fig. 2 is a longitudinal vertical section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a transverse vertical section on an enlarged scale taken on the line 8-3 of Fig. l, the several folds of the work sheet web being shown and spaced apart for clarity.

In the particular drawing selected for more fully disclosing my invention, which will be understood to be illustrative merely and not restrictive, it is a continuous work sheet web folded laterally in zigzag form, there being in the present instance four such folds, the work sheet shown having blank forms to be filled in on a typewriting machine. Interleaved between the respective folds of the web are individual unfolded transfer sheets ll, each substantially coextensive with the folds of the work sheet. The transfer sheets are provided with registering notches i2 at one edge thereof, said notches being cut into the upper edge of the transfer sheets in the present instance, although it will readily be understood by those skilled in this art that they may be otherwise placed.

Each of the folds of the web is provided with laterally extending lines of weakness l3, such as indentations, perforations, or the like. As

' indicated in Fig. 2, the lowermost edges of the folds beyond the line of weakness, constitute the stub portion of the packet, and the several parts thereof, viz., the ends of the blank forms and transfer sheets, are unattached laterally, that is to say, the folds are connected to each other only at their alternate longitudinal edges, as indicated at M, ii, in Fig. 3.

In use the upper edge i of the packet is inserted between the gripping rollers of a typewriting machine, the forms filled in, and then after the packet is removed, the operator grips the stub portion of the same below the line of weakness i3 and at the upper edge thereof over the cutout portions of the transfer sheet so that the folds of the web only are held and not the transfer sheets, and then by a quick movement, tears the folded web away from the lowermost end thereof along the line of weakness; the transfer sheets, which are known as one-time carbon" remaining in one hand of the operator, together with the lowermost edges of the web.

The several advantages of the packet constructed in accordance with my invention are the ease with which the fanfolded forms can be loaded by inserting the individual transfer sheets and then "jogging" the packet against a flat surface by holding it a few inches above such surface and allowing the lower edge to strike sharply against the surface; the ease whereby the packet can be packed in cartons for shipment, as distinguished from several types of packets now in use in which the transfer sheets extend beyond the edges of the web, sometimes the longitudinal edges and sometimes the lateral edges, and in some cases, both, in contradistinction to being coextensive with' the folds of the web; the facility whereby the lower portion of the lowermost form may be typed due to the fact that the stub or portion of the packet below the line of weakness will be still in contact with the gripping rollers of the machine while the last line is being typed on the lowermost form.

My improved packet has other advantages, one of which is that as the lowermost edges of the folds are unattached laterally and not pasted together or stapled as heretofore has been the practice, no bulge is formed as the lower portion of the packet passes through the gripping rollers and there is no tendency for the severance of the packet from the stub at the line of weakness, although in packets in which the elements are secured by stapling, pasting, or otherwise, the formation of such bulge and the resulting strain on the web and transfer sheets frequently effects the severance of the stub from the packet in whole or in part. Also, due to the absence of staples or other holdfast means, extra work sheets and carbons can readily be inserted in cases where the press cannot print a sufllcient number of form sheets. For example, in the present instance, it will be assumed that the capacity of the press is four work sheets, i. e., a web which when folded in the manner shown provides only four such sheets, and a user requires a packet having five. In such case, one work sheet with a sheet of carbon may readily be inserted between the first fold and its carbon; and in like manner, if six or seven work sheets are required, the extra sheets and carbons may be inserted between the second and third work sheets and/or the third and fourth.

Having thus described an illustrative embodiment of my invention without, however, limiting the same thereto, what I claim and desire tosecure by Letters Patent is: i

A maniioldin: packet. comprising a. continuous unnotched work sheet web tolded laterally in zigzag form and individual unfolded transfer sheets interleaved between the respective folds of said web, said transfer sheets being substantially coextensive with said folds and having registering notches at one edge thereof removed from the hereinafter mentioned stub portion of the packet. each fold of said web bein: provided with a laterally extending line of weakness adjacent the lower edge thereof and the lowermost edges or said folds beyond said line of weakness constituting the stub portion or the packet. the parts of said stub portion being unattached laterally.
